Research Abstract

Some phenyleneethynylene molecular wires having two nitronyl nitroxide radicals were synthesized to investigate the decay constant of p-phenyleneethynylene. By the measurement and simulation of the ESR spectra of the biradicals with different wire length, it was found that the exchange interaction was decreased with the decay constant beta of 0.38 A^-1. This result indicates that the spin-spin exchange interaction between neutral radicals has a similar decay constant to the molecular conductance.
